The embodiment of the invention discloses a power supply circuit of an electric trailer and the electric trailer. The power supply circuit of the electric trailer comprises an energy supply module used for outputting electric energy; the first power distribution module is connected with the energy supply module, and the first power distribution module is used for being connected with a first load and outputting electric energy to the first load, or converting braking energy of the first load into electric energy and transmitting the electric energy to the energy supply module; the second power distribution module is connected with the energy supply module, and the second power distribution module is used for being connected with a second load and outputting electric energy to the second load; the rated voltage of the first power distribution module is higher than that of the second power distribution module; the rated voltage of the first load is higher than that of the second load. According to the technical scheme, energy supply of the electric trailer is stable, the requirements of different working conditions can be met, the problems that the endurance of the electric trailer is short, and use of the electric trailer under different working conditions is limited are solved, and the use reliability of the electric trailer is improved.

    本发明实施例公开一种电动挂车的供电电路及电动挂车。该电动挂车的供电电路包括供能模块,用于输出电能;第一配电模块,与供能模块连接,第一配电模块用于连接第一负载,并向第一负载输出电能,或者,将第一负载的制动能量转换为电能传输至供能模块;第二配电模块,与供能模块连接,第二配电模块用于连接第二负载,并向第二负载输出电能;第一配电模块的额定电压高于第二配电模块的额定电压;第一负载的额定电压高于第二负载的额定电压。本实施例提供的技术方案使得电动挂车的供能稳定,并能满足不同工况的需要,解决了电动挂车存在续航较短,限制电动挂车在不同工况下的使用的问题,改善了电动挂车的使用的可靠性。
